The Chicken or the Egg? The Scientific Design Behind Human Birth and the Proof of a Creator

The classic question “Which came first, the chicken or the egg?” touches on one of the most profound mysteries in nature. It reflects a broader challenge found in countless biological systems — mechanisms composed of multiple interdependent parts, where the absence of even one component renders the entire system nonfunctional.

In such systems, everything must appear together and work in perfect harmony, for life to exist. This question can be asked not only about chickens but also about the birth of humans themselves.

The Impossible Design of Human Birth

Human beings have a much larger brain relative to body size than other animals. A human baby’s head is significantly larger than that of a newborn ape, and yet a mother’s cervix is too narrow to allow such a large head to pass through safely.

This presents a stunning biological paradox:

• Without a skull, the baby cannot survive inside or outside the womb.

• If the skull were complete and solid, the baby could never be born.

• The cervix cannot simply expand further without endangering the mother’s life.

From any angle, human birth seems impossible.

The Perfect Solution: A “Puzzle-Like” Skull

The solution is astonishing in its precision: the human skull is born in pieces. A baby’s skull is made up of separate flexible plates joined by soft seams called fontanelles. This ingenious design allows the skull to compress and stretch like soft dough during birth, passing safely through the birth canal without harming the baby or the mother.

Once outside the womb, the skull slowly returns to its normal shape.
These plates fuse together over time — leaving the soft spot on a baby’s head that parents recognize as the fontanelle. This area is covered by tough protective membranes that guard the brain while still allowing flexibility.

Without this exact system of four perfectly positioned openings (front, back, and sides) that close at just the right pace, human life could not exist. A single deviation in size, location, or timing would be fatal.

• The posterior fontanelle closes at around four months after birth.

• The anterior fontanelle closes at around eighteen months.

If these gaps closed too early, the baby’s brain couldn’t grow, but if they closed too late, the skull would remain dangerously soft. The precision of this biological mechanism is beyond comprehension.

The Miracle of Mother's Milk

The miracle doesn’t stop there. The newborn needs mother’s milk to survive. For thousands of years, no substitute existed — and even modern formula cannot replicate it.

Mother’s milk provides not just nutrition but also vitamins, antibodies, and immune support perfectly tailored to the baby’s needs. It contains over 200 unique components, and its composition changes automatically:

• In hot weather, it contains more water.

• As the child grows, it contains more fat and nutrients.

Even the mother’s diet has little impact on milk composition — ensuring the baby’s nourishment even in times of scarcity.

The newborn, though nearly helpless and barely able to see, instinctively finds the source of milk and knows how to suckle. If this instinct did not exist from the very first birth, no mammal could have survived. Modern research shows that even in the womb, human fetuses practice the sucking motion in preparation for birth.

Why Evolution Cannot Explain It

These examples of the flexible skull, breast milk, and the suckling instinct, are all multi-part systems that cannot function unless every component exists simultaneously.

This is what modern biochemist Professor Michael Behe calls “irreducible complexity” — systems so intricately interdependent that they could not have evolved gradually, because incomplete versions would not work at all.

Charles Darwin himself admitted in The Origin of Species: “If it could be demonstrated that any complex organ existed which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down.”

Behe’s landmark book Darwin’s Black Box presents molecular-level examples of such systems, proving that life’s complexity points to intelligent design.

The Limits of Natural Selection

Even if evolution were possible in principle, it cannot explain how so many precise, beneficial mutations appeared at the same time.
Natural selection can only “filter” existing mutations, but cannot create them. Needing a mutation does not guarantee its appearance, just as a poor man’s need for gold does not make a treasure chest fall from the sky.

The number of coordinated genetic “coincidences” required for human survival defies probability. The DNA code appears as if written deliberately — with purpose and foresight.

Thus, even if one accepts evolution as a physical process, it could only exist under divine supervision — a Creator timing each genetic step to form the magnificent order we see in nature.

Two Scientific Paths That Point to God

From the study of life and its mechanisms, we find two complementary proofs of divine creation:

1. Irreducible Complexity – “The Chicken or the Egg” problem: Interdependent biological systems that could not arise in gradual stages but only through instant, coordinated creation.

2. Statistical Impossibility – The overwhelming improbability that so many “successful mutations” could occur by random chance, implying an intelligent guiding hand behind life.

Every intricate detail of human birth, nourishment, and survival bears the unmistakable signature of design. The structure of the infant skull, the production of milk, the newborn’s instinct — all reveal a purposeful Creator who engineered life with infinite wisdom and precision.
